Embodiment
Below in conjunction with accompanying drawing of the present invention, be clearly and completely described the technical scheme in embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the invention provides a kind of such as light fixture or enter the controlled device of wall switch, this device mainly comprises: the gesture of such as display screen applies parts, by applying the control that effective gesture can realize this controlled device on the components, such as, control by implementing various correspondence to the display screen entering wall switch and carry out switch control rule the operations that gesture can realize this switch; And the multiple range sensors on each side of these parts, such as, four range sensors A, B, C, D respectively on these four sides of the left side of parts, upside, right side and downside.Above-mentioned range sensor, for judging the distance of restraining mass and sensor itself, can use ultrasound wave or active infrared correlation technique to realize, such as, adopt active infrared transmission and reception to realize pipe.When object is near described range sensor, output voltage becomes large, MCU is according to the distance of AD sampled value judgment object, its concrete hardware implementation mode is the infrared signal that control NE555 time switch infrared transmitting and receiving tube reception object returns, receiver voltage is amplified by TLC2272 discharge circuit, export AD interface to, AD sampling obtains distance parameter.
The distance parameter obtained and the distance parameter obtained and a preset parameter are contrasted, judges that when the distance parameter that this obtains is less than or equal to a preset parameter this respective distance sensor is blocked by object.Such as, for some range sensors of specifying, such as, for range sensor A, when having the front of its direction of measurement of object proximity to when being less than or equal to preset parameter, event of namely blocking occurs, and we are defined as A event and occur.Accordingly, the event of blocking that we can obtain other range sensors B, C, D is respectively B event, C event, D event etc.
First, the aforementioned corresponding arrangement composite sequence blocking event is defined, it to be associated with each corresponding operating of controlled device.Such as the arrangement of objects composite sequence that blocks that gesture motion as shown by arrows in Fig. 1 produces is defined as "left turn", if the display screen of this controlled device detects this effective permutation and combination sequence, this controlled device can realize "left turn" operation, namely make the information in display screen can convert the information of " left side " one page to.By that analogy, the corresponding various gesture that the switching manipulation such as "right turn", " above turning over ", " under turn over ", " rollback ", " refreshing " is corresponding can also be defined.
When user is successively close to range sensor described above, just obtain certain possible permutation and combination that the events such as A, B, C, D occur successively.First, define a time parameter T, when the interval time only having two adjacent events to occur is at the appointed time within T, just can obtain effective composition of matter.Such as, as shown in Figure 2, suppose user successively close to 4 range sensors, obtain event A, B, C, D respectively.The time interval simultaneously making A, B event occur is T1; The time interval that B, C time occurs is T2; The time interval that C, D time occurs is T3; And there is no other events after D event, before A event, there is no other events yet.Wherein find T1<T, T2<T, T3>T through contrast.Owing to not having other events before A event, so when A occurs, we obtain first and are input as A, due to the time interval T1<T between A, B event, therefore, it is possible to obtain effective composition of matter AB, so first input becomes AB, due to the time interval T2<T between B, C event, therefore, it is possible to obtain effective composition of matter AB and BC simultaneously, now integrated by above-mentioned composition of matter AB and BC, the permutation and combination sequence just obtaining first input becomes ABC, due to C, time interval T3>T between D event, therefore corresponding composition of matter CD is invalid, namely when timing T arrives, next event D not yet occurs, so effective composition of matter CD can not be obtained, therefore this composition of matter CD can not be counted in composition of matter sequence, now the permutation and combination sequence of first input is still ABC, and this event end of input, the list entries finally obtained is ABC, now this controlled device can implement the corresponding operation of permutation and combination sequence A BC effective in this, and will restart to record next input, when event D occurs, we obtain second input D, owing to not having other events after D, therefore next event is not had to occur when timing T arrives, so obtain second is effectively input as D.
When as previously mentioned once obtain effective permutation and combination sequence, just controlled device is made to implement corresponding operating according to the corresponding relation defined before.Such as shown in Figure 1, create a gesture motion as shown by arrows, and this gesture motion is less than or equal to schedule time T from sensors A to the event of sensor C, according to description above, we can obtain effective incoming event is AC, and this AC event is defined as "left turn" as previously mentioned, so when above-mentioned gesture occurs and obtained this effective permutation and combination sequence A C by device detection, this controlled device can realize "left turn" operation, therefore, it is possible to make the information in display screen convert the information of " left side " one page to.By that analogy, the operation that can realize corresponding corresponding various gesture according to the Operation Definition such as the "right turn" defined, " above turning over ", " under turn over ", " rollback ", " refreshing " controls.
As above described in above embodiment, by applying multiple range sensor in the controlled device such as entering wall switch or light fixture, and by various effective gesture that described multiple range sensor sensing user is implemented this controlled device, and described various effective gesture is defined corresponding with the operations of this controlled device, can obtain the non-contact gesture identification control method that a kind of controlled device that can carry out gesture identification also can realize this device, thus the intellectuality achieving device controls flexibly.
Those skilled in the art of the present technique are appreciated that various operations, method, the step in flow process, measure, the scheme discussed in the present invention can be replaced, changes, combines or omit.Further, there is various operations, method, other steps in flow process, measure, the scheme discussed in the present invention also can be replaced, change, reset, decompose, combine or omit.Further, of the prior art have also can be replaced with the step in operation various disclosed in the present invention, method, flow process, measure, scheme, changed, reset, decomposed, combined or omitted.
The above is only some embodiments of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement and adjustment, these improve and adjustment also falls within the scope of protection of the present invention.
